Call center resource processor

ABSTRACT

The invention provides a call processing system to handle calls to a call center by obtaining absolute address for a call center resource from a call center resource processor prior to directing the call to the call center resource. The invention includes a call center resource processor that receives an address query from a communications system for an absolute address of a call center resource. The call center resource processor processes the address query to identify the absolute address. After identifying the absolute address, the call center resource processor generates an address response with the absolute address for the call center resource. The call center resource processor transmits the address response with the absolute address from the call center resource processor for the communications system to route the call using the absolute address. At the call center resource, no translation of the call is needed to direct the call to the call&#39;s final destination, an agent, interactive voice response, or voice response unit. Therefore, complex routing equipment at the call center resource can be eliminated. Because the absolute address is identified at the call center resource processor, the invention may also transmit service data over the same communications equipment as the call from the network element system to the call center resource. Separate communications equipment at the call center resource for service data can be eliminated.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention is related to the field of call processing systems, and in particular, to a system that routes calls to a call center.

2. Description of the Prior Art

Call processing is a key component to companies looking to compete in rapidly growing global markets. Call processing is essential to companies for entering sales orders, furnishing product or service information, and providing customer service. The increasing number of calls handled by a call center and the need for expanding service to new geographic regions introduce new demands to call center processing. In order to meet these demands, companies are increasing their number of call centers to provide better customer service such as extended hours of operations and service agents fluent in the caller's native language. One call center could provide for continuous operating hours and a diverse array of foreign language agents. However, constraints such as graveyard shifts and lack of ethnic diversity in a certain geographic region make a one call center solution difficult. Other solutions such as different “800” numbers based on language or hours of operations are confusing to the consumer and thus impractical. Greater number of call centers can also improve customer service by reducing queuing times through diverting calls to less occupied call centers.

A flexible and robust call processing solution with an expansive network of call centers is needed. An important factor in providing an operable solution is to minimize costs. Simplifying each call center down to the service agent assists in reducing costs and implementation times. Less implementation of call processing equipment can further reduce unneeded costs. In the event that a call center becomes impaired, the call processing solution should be flexible enough to route calls to alternate call centers. Implementation of new call processing schemes should be uniform and rapid across the network of call centers. Companies also require usage and call information to monitor call centers usage and improve future call processing designs. Ultimately, companies need greater freedom to employ their own provisioning, managing, and billing tools for their call centers.

One current system uses a telephone circuit switch to receive calls and signaling into a network. The telephone circuit switch processes the called number to generate and transmit a first query to a Service Control Point (SCP). The SCP processes the first query to generate a second query to a routing processor at a call center. The routing processor at the call center responds to the SCP with routing information, and the SCP responds to the telephone circuit switch with the routing information. The telephone circuit switch then extends the call to another telephone circuit switch connected to the call center based on the routing information. This other telephone circuit switch then transfers the call to the call center over a dedicated Time Division Multiplexing (TDM) line, such as an Integrated Services Digital Network (ISDN) connection. This transfer includes a transfer of the called number. Routing equipment at the call center must process the called number to internally route the call to the destination within the call center. This system is deficient because it forces the routing equipment at the call center to handle dialed number processing. It also does not allow the efficient utilization of packet-based transport technologies.

Another current system uses a telephone circuit switch to receive calls and signaling into a network. The telephone circuit switch processes the called number to generate and transmit a first query to a Service Control Point (SCP). The SCP responds to the telephone circuit switch with the routing information. The telephone circuit switch then extends the call to a service platform using Extended Superframe (ESF) or ISDN connections. The service platform processes the called number to generate a second query to a routing processor at a call center. The routing processor at the call center responds to the service platform with routing information. The service platform then extends the call to another telephone circuit switch connected to the call center based on the routing information. This other telephone circuit switch then transfers the call to the call center over a dedicated TDM line, such as an ESF connection or an ISDN connection. This transfer includes a transfer of the called number. Routing equipment at the call center must process the called number to internally route the call to the destination within the call center. This system is deficient because it forces the routing equipment at the call center to handle dialed number processing. It also does not allow the efficient utilization of packet-based transport technologies.

SUMMARY OF THE INVENTION

The invention solves the above problem by providing integrated broadband call processing that uses a call center resource processor to determine how to route calls to the call center. The invention includes a call center resource processor that receives an address query from a communications system for the absolute address of a call center resource. The “absolute” address is a hardware address of a device used to initially answer the call at the call center. The absolute address is contained in packets for the call. Some examples of absolute addresses are a port identifier, Media Access Control (MAC) layer address, and Asynchronous Transfer Mode (ATM) address. The absolute address does not require translation at the call center to identify the answering devices. In contrast, telephone numbers require translation to identify a terminating point or telephone. The call center resource processor processes the address query to identify the absolute address for the call center resource. After identifying the absolute address, the call center resource processor generates an address response with the absolute address for the call center resource. The call center resource processor transmits the address response with the absolute address from the call center resource processor for the communications system to route the call using the absolute address. In one embodiment, the invention identifies the call center resource by which call center resource is available and capable to handle the call.

The invention allows the call center and communications network to efficiently utilize packet-based transport technologies. This results in the elimination of complex routing equipment at the call center site. Routing can now be passive at the call center resource level since the call can be routed directly to the service agent or voice response unit based on the absolute address. Any address translation such as dialed number processing at the call center resource level can be removed.

Another advantage from utilizing packet-based transport technologies is the reduction of routing equipment for separate data lines for service data. Service data is data associated with the call or data derived from the call. Some examples of service data include caller name and address, service scripts, or other screen pop information. In a screen pop operation, service data such as customer profile and product and service information pops up on the agent's computer when the agent receives the incoming call. Because the call processing system already has the absolute address for the call, the invention can now transmit the service data in data packets using the absolute address over the same line as the call. Therefore, separate, dedicated routing equipment for service data is eliminated at the call center resource level.

The invention allows telephone companies to provide a flexible and robust call processing system to companies requiring call center services. Removing the call processing at the call center site level and centralizing the call processing at a call center resource processing level satisfies many of the call center companies' needs. A centralized call center resource processor can monitor call center for overuse and redirect calls to underutilized call centers. The invention provides one phone number access to multiple call centers with increased hours of operations and foreign language agents. Centralization to a call center resource processor will also reduce implementation times of new call center processing designs by eliminating implementations at each call center site. The centralized call center resource processor provides greater flexibility to companies to configure their call processing based on their needs.

The invention may also provide absolute, real-time usage information for the call to the call center resource processor. The call center resource processor can record service data and call information, while also monitoring call center resource availability and bottlenecks. This information can then be used as a basis for new center processing designs and decisions regarding usage of call center processing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

System Configuration and Operation—FIGS. 1-2

An advantage of using an absolute address to transfer a call from a communications network to a call center resource is that it allows the call center and communications network to handle the call center resources in a real time, precise fashion. This results in the elimination of complex, dedicated routing equipment at the call center, since the call can be routed within the call center using the absolute address that is in the call packets when the call center receives them. No longer will duplication of call processing equipment be needed at every call center. Instead, call processing equipment can be centralized at the call center resource processor.

An advantage of obtaining an absolute address from a call center resource processor is that it provides greater flexibility for call center operators to employ their own process for handling incoming calls. Centralization of call center processing can lead to a more dynamic call center architecture and reduction of implementation times of new design features of call center processing. Call center operators can freely configure their global call center network to improve customer service by reducing call queuing time and optimizing use of call centers.

Another advantage is service data such as customer data and product and service information can be routed directly to the call center resource using the absolute address. The service data is transmitted to the call center resource over the same communication equipment as the call is transmitted. Thus, dedicated communication equipment for providing service data to the call center resource are eliminated.

FIG. 1 depicts a communications system 100 coupled to a call center 120 by a control link 110 and a call link 112. The communications system 100 is comprised of a call processing system 102 and a network element system 104 connected by a control link 114. A signal link 106 connects to the call processing system 102. A call link 108 connects with the network element system 104. The call center 120 is comprised of a call center resource processor 122 and a call center resource 124 connected by a control link 126. The control link 110 connects call processing system 102 and call center resource processor 122. The call link 112 connects the network element system 104 and the call center resource 124.

The call processing system 102 could be any computer processing platform that: 1) receives and processes the signal for a call to select a call center resource processor 122, 2) generates and transmits an address query for the call center resource processor 122, 3) receives an address response from the call center resource processor 122 that includes an absolute address for the call, and 4) processes the address response to generate and transmit a route instruction to cause the network element system 104 to route the call to the call center resource 124 using the absolute address. The call processing system 102 may also receive service data from the call center resource processor 122 and transmit the service data to the network element system 104 for delivery to the call center resource 124 using the absolute address.

The network element system 104 represents any communications device or combination of devices that: 1) receives the call, 2) receives the route instruction containing the absolute address for the call, and 3) transfers packets containing the call to the call center resource 124 using the absolute address obtained. One embodiment of the communications system 100 is further described below in FIGS. 9-47.

The call center resource processor 122 could be any computer processing platform that: 1) receives the address query for the absolute address, 2) processes the address query to identify the absolute address for a call destination within the call center resource 120, and 3) generates and transmits the address response with the absolute address. The call center resource processor 122 may also generate and transmit the service data to the call processing system 102.

The call center 120 is a call destination that is typically external to the communications network 100 and handles high-call volumes. The call center includes many call center resources 124 that answer calls and interact with the caller to provide services such as order taking or customer service. Call centers and call center resources are well known.

To transfer the call to the call center 120, the network element system 104 transfers packets containing both the absolute address and the call to the call center 120. The call center 120 uses the absolute address to route these packets to a call destination within the call center resource 124. It should be noted that the call center 120 does not need to translate the absolute address in order to route the call packets to the destination. Phone numbers and internet addresses need some translation to hardware address such as a MAC layer address. The “absolute” address is a hardware address of a device used to initially answer the call at the call center 120. Some examples of absolute addresses are a port identifier, MAC-layer address, ATM address, or call processing thread unique to the person or voice response unit (VRU) receiving the call. The absolute address is contained in call packets. An advantage to identifying the absolute address is no translation is needed at the call center resource 124.

The term “processor” could mean a single processing device or a plurality of inter-operational processing devices. Some examples of processors are computers, microprocessor chips, integrated circuits, and logic circuitry. A particular reference number in one figure refers to the same element in all of the other figures.

FIG. 2 depicts a message sequence chart for the call processing system 102, the call center resource processor 122, the network element system 104, and the call center resource 124 in accordance with the invention. The initial signal comes through the signal link 106 to the call processing system 102. The call processing system 102 processes the initial signal to select the call center resource processor 122 and generates the address query. In alternative embodiments of the invention, the call processing system's 102 processing of the initial signal to select the call center resource processor 122 can be based upon the caller number, the called number, or caller entered digits such as a personal identification number or an account code. The call processing system 102 transmits the address query through the control link 110 to the call center resource processor 122. Upon receipt of the address query, the call center resource processor 122 processes the address query to identify the absolute address for the call center resource 124. The call center resource processor 122 also generates the service data. Service data is data associated with the call or data derived from the call. Some examples of service data are Automatic Number Identification (ANI), customer information, items previously ordered by the caller, web pages containing data, and prompting information. The service data could be used to pop up a screen with this information at the agent's computer. The call center resource processor 122 replies with an address response including the absolute address and the service data back through the control link 110 to the call processing system 102.

The call processing system 102 processes the address response to generate a route instruction to cause the network element system 104 to route the call to a call center resource 124 in call packets containing the absolute address. The call processing system 102 then transmits the route instruction including the absolute address through the control link 114 to the network element system 104. The call processing system 102 transmits a data instruction to cause the network element system 104 to route the service data to the call center resource 124 in data packets containing the absolute address to the network element system 104 through the control link 114. The call processing system 102 also transmits the service data to the network element system 104 through the control link 114. The network element system 104 receives the call over the call link 108. In response to the receiving the route instruction, the network element system 104 routes the call to the call center resource 124 through the call link 112 using call packets that contain the absolute address from the route instruction. The network element system 104 also transmits the service data to the call center resource 124 through the call link 112.

Once the call terminates, a release signal is received into the call processing system 102 through one of the links 106, 110, or 114. The call processing system 102 transmits an instruction to terminate the call to the network element system 104 through the control link 114. In response to a call release, the call processing system 102 generates call information. Call information concerning the call is then sent from the call processing system 102 to the call center resource processor 122 through the control link 110. Call information is information related to the call's operation. Some examples of call information are caller number, dialed number, absolute address, time of call, call duration, system usage time, number of resources used, origin of call, and identification of call center receiving call. Call center resource 124 also transmits service data via the control link 126 to the call center resource processor 122.

Broadband Distributed Call Center Communication System—FIGS. 3-8

FIGS. 3-8 disclose a distributed configuration of the invention, but the invention is not restricted to the configuration provided below. Those skilled in the art will appreciate numerous variations in routing system configuration and operation that are within the scope of the invention. Those skilled in the art will also appreciate how the principles illustrated in this example can be used in other examples of the invention.

FIG. 3 depicts system level block diagram of a distributed configuration of the invention. A telephone 302 is connected to a local telephone switch 306 via a call link 304. Linked to the local telephone switch 306 is a service control point (SCP) 308. A broadband distributed call center communications system 300 is comprised of a communications system 326, a service control point (SCP) 314, and a communications system 342. The communications system 326 includes a call processing system 316 and a network element 320 linked by a control link 318. A signal link 310 connects the local telephone switch 306 to the call processing system 316. A call link 312 connects the local telephone switch 306 to the network element 320. The SCP 314 is linked to the call processing system 316. The call processing system 316 is connected to a call center resource processor 324 by a control link 322.

The communication system 326 is coupled to a communication system 342 by an ATM connection 330 and a Transmission Control ProtocoJIntermet Protocol (TCP/IP) connection 328. The communication system 342 is comprised of a call processing system 332 and a network element 336 connected by a control link 334. The SCP 314 is linked to the call processing system 332. The TCP/IP connection 328 connects the call processing system 316 with the call processing system 332. The ATM connection 330 connects the network element 320 with the network element 336. The ATM connection 330 typically includes ATM switches that use a Network to Network Interface (NNI). A call center 344 is comprised of a call center resource processor 324 and a call center resource 340 connected by a control link 346. A call center resource 340 is connected to the network element 336 by an ATM link 338.

FIG. 4 depicts the call center resource processor 324. The control link 322 connects to an Ethernet TCP/IP network 400. The Ethernet TCP/IP network 400 is connected to a pre-routing processor 402, a call center database 404, a resource management processor 406, a force management processor 408, a post-routing processor 410, an ESP host Interactive Voice Response (IVR) manager 412, and a call center report processor 414.

The pre-routing processor 402 could be any computer processing platform that: 1) receives and processes an address query for an absolute address, 2) retrieves data from the call center database 404, 3) identifies an absolute address based on characteristics of the call and the call center resource information from the call center database 404, and 4) transmits an address response for the call processing system 316 containing the absolute address. The pre-routing processor 402 can also query the call center database 404, receive service data from the call center database 404, and transmit service data to the call processing system 316. The pre-routing processor 402 can identify the absolute address based on numerous criteria from the call and the call center resource. The invention is not limited to the following examples of criteria used in identifying the absolute address. The time of the day or the exact day could be used to route nighttime calls to daytime call center resources or play an Interactive Voice Response (IVR) for a holiday greeting. The exact day could be based on day of the week of day of the year. Caller specific information such as ANI, Dialed Number Identification Service (DNIS), geographic region of the caller, a called number, and caller entered digits could also be used to route 800 number employee benefit calls to agents handling a specific company. Allocation of call center resources based on percentages of call centers resources to calls, load balancing, trends, or maximum/minimum/average call quotas could be used to route calls to underutilized call center resources. The pre-routing processor 402 checks an availability indication if the call center resource is available. The pre-routing processor 402 also checks capability data to match call center resources that are capable to handle the call. Examples of call center capabilities are language, gender, age groups, education, income levels, seniority level, skill level, agent's knowledge of a subject, industry experience. The pre-routing processor 402 may also route calls to agents based on the distance between the caller and the call center resource.

The resource management processor 406 could be any computer processing platform that 1) obtains an availability indication for the call center resource, 2) obtains capability data for the call center resource, 3) obtains an association of an absolute address with the call center resource, and 4) transfers information to the call center database 404 associating the absolute address for the call center resource with the availability indication and the capability data for the call center resource. The availability indication reflects that the absolute address for the call center resource can be used to handle calls. The resource management processor 406 obtains an unavailability indication for the call center resource and updates the call center database 404 to reflect that the absolute address for the call center resource cannot be used to handle calls. The resource management processor 406 obtains another availability indication for the call center resource and updates the call center database 404 to reflect that the absolute address for the call center resource can be used to handle calls. The invention is not limited to the following capabilities of call center resources. Capabilities such as language, sex, age groups, education, and incomes can be matched between caller and call center resources. Priority customers may be matched with the senior agents to provide the best service. The agent's skills, knowledge of a subject, or industry experience may be used to match calls with a specific need. Also, skill levels may be configured to have more experienced agents receive calls before inexperienced agents.

The force management processor 408 could be any computer processing platform that 1) assists in planning the future capacity of the call center resources and 2) updates the call center database 404 with the planning information. Planning future capacity entails handling overflow and staffing pools of call center resources. Once the planning has been completed, the force management processor 408 will update the call center database 404, so the planning information can be available to other system components.

The post-routing processor 410 could be any computer processing platform that 1) receives and processes an address query for an absolute address, 2) retrieves call center resource information from the call center database 404, 3) identifies an absolute address based on characteristics of the call and the call center resource information from the call center database 404, and 4) transmits a transfer response to transfer the original call 316 to the absolute address. The post-routing processor 410 can identify the absolute address in the same manner as the pre-routing processor 402 identifies the absolute address as discussed above. The post-routing processor 410 may also receive data from the ESP host IVR manager 412.

The ESP host IVR manager 412 could be any computer processing platform that 1) determines which Interactive Voice Response (IVR) or Voice Response Units (VRU) are available, 2) determines which IVRs or VRUs are capable to handle the calls, and 3) updates the call center database 404 with the availability and capability information of the IVRs and VRUs. The ESP host IVR manager 412 may also play scripts made up of predefined building blocks that perform different call related functions. The building blocks could be comprised of various combinations of call related functions including, but not limited to, 1) capturing caller entered digits, 2) routing calls to IVRs, VRUs, or agents based on service data, 3) playing pre-recorded messages based on service data, date, or time of day, 4) capturing and validating of caller entered digits, and 5) collecting call information for reports. Based on the scripts, the ESP host IVR manager 412 can either perform the call related function or route the call to a IVR, VRU, or agent to perform the call related function.

The call center report processor 414 receives service data and call information and stores the service data and call information. The call center report processor may generate reports based on the service data and call information. The call center report processor 414 may receive service data including, but not limited to, ANI, caller entered digits, residential or pay phone identification, city, address, frequency of calls, payment status, last call, reason for call, outcome, and customer satisfaction. The call center report processor 414 may receive call information including, but not limited to, agent availability, agent readiness, talk time, queue time, abandon rate, number of retries, busy rate, network availability, time transferred, call length, VRU time, and wrap-up time.

FIG. 5 depicts the call center resource 340. The ATM link 338 connects an ATM switch 500 to the network element 336 and uses a User to Network Interface (UNI). An ATM network 502 is connected to an ATM switch 500, the control link 346, an interactive voice response unit 504, an agent position 506, and an access server 508. An agent position 510 is linked to an access server 508 by an Integrated Services Digital Network link 524. An agent position 514 is connected to the access server 508 via a 100Mb link 512. An authorization database 516 is linked to the access server 508. A Point-to-Point Protocol link 518 connects the access server 508 and a modem 520. An agent position 522 is connected with a modem 520.

FIG. 6 depicts a message sequence chart for the distributed configuration of an example of the invention. The telephone 302 initializes the call through the call link 304 to the local telephone switch 306. The local telephone switch 306 transmits an Initial Address Message (LAM) signal using the Signaling System 7 protocol to the call processing system 316 via the signal link 310. In another embodiment, the local telephone switch 306 may also generate the routing query to the SCP 308 that replies with routing instructions. Upon receipt of the initial signal, the call processing system 316 transmits a SCP query to the SCP 314 to select the call center resource processor 324. The SCP 314 responds to the call processing system 316 with a SCP response. Another embodiment of the invention does not query the SCP for selecting the call center resource processor 324. After the receipt of the SCP response, the call processing system 316 transmits an address query to the call center resource processor 324 via the control link 322 for the absolute address of a call center resource 340 for the call. The call center resource processor 324 receives the address query and transmits the address response with the absolute address and the service data back to the call processing system 316 through the control link 322. Once the address response with the absolute address is received, the call processing system 316 then transmits a route instruction to the network element 320 via the control link 318 to route the call to the network element 336. The call processing system 316 transmits a data instruction to the network element 320 via the control link 318 to route the service data to the call center resource 340. The call processing system 316 also transmits the service data to the network element 320 through the control link 318.

After the absolute address is obtained, the call processing system 316 transmits route information with the absolute address to the call processing system 332 via the TCP/IP connection 328. The call processing system 332 transmits the route information with the absolute address to the network element 336 via the control link 334. The call is sent from the local telephone switch 306 to the network element 320 via the call link. Using NNI, the call is sent from the network element 320 to the network element 336. Using UNI, the network element 336 routes the call in packets to the call center resource 340 via the ATM link 338. The network element 336 places the absolute address in the call packets in response to the route information from the call processing system 332. The service data in data packets follow a similar path from the network element 320 to the call center resource 340. When the call terminates through the telephone 302, a release signal is sent to the call processing system 316. Upon termination of the call, call information is sent from the call processing system 316 to the call center resource processor 324. The call center resource 340 also transmits the service data to the call center resource processor 324 via link 346 at the termination of the call to update the call center resource processor if service data has changed. In a different embodiment, the call center resource 340 may transmit the service data for the call center resource processor via network element 336, network element 320, and call processing system 316.

Another embodiment of the invention includes the address query from the SCP 314 to the call center resource processor 324 for the absolute address instead of the address query originating from the call processing system 316. The call processing system 316 transmits a SCP query to SCP 314 to generate the address query for the call center resource processor 324. After receiving the SCP query, the SCP 314 transmits the address query to identify the absolute address of the call center resource 340 for the call center resource processor 324. The SCP 314 receives the address response including the absolute address and the service data from the call center resource processor 324. The SCP 314 then transmits the SCP response including the absolute address and the service data to the call processing system 316.

FIG. 7A depicts a message sequence chart for the call center resource processor 324. The resource management processor 406 transmits the resource information related to the availability and capability of the call center resource 340 to the call center database 404. The resource management processor 406 updates the call center database 404 with the resource information when the state of the call center resource 340 changes such as an agent becoming available. The force management processor 408 transmits the planning information for the call center resource 340 to the call center database 404. The force management processor 408 can update the call center database 404 with the planning information at regular time intervals like every five minutes. The call center database 404 will then have all the call center resource's 340 availability and capability information for identification of an absolute address.

The call processing system 316 transmits the address query to the pre-routing processor 402 for an absolute address to route the call to. The pre-routing processor 402 then transmits a database query to the call center database 404 and receives the resource information from the call center database 404. The pre-routing processor 402 also receives the service data from the call center database 404. The pre-routing processor 402 then transmits an ESP query to the ESP host IVR manager 412 for prompting information. The ESP host IVR manager 412 can play a script to receive prompting information such as customer entered digits. Other variations of scripts are discussed above. The ESP host IVR manager then transmits the prompting information to the pre-routing processor 402.

The pre-routing processor 402 then identifies the absolute address based on the resource information. The pre-routing processor 402 may also base identification on any service data including the prompting information. After identification, the pre-routing processor 402 transmits an address response with the absolute address and the service data to the call processing system 316 through the control link 322.

FIG. 7B depicts a continuation message sequence chart for the call center resource processor 324. In FIG. 7B, if the call needs to be transferred to another agent, the call processing system 316 transmits a transfer query to the post-routing processor 410 for an absolute address. The post-routing processor 410 then receives the transfer query and transmits a database query to the call center database 404. The post-routing processor 410 then receives the resource information related to the availability and capability of the call center resource 340 from the call center database 404. The post-routing processor 410 then identifies the absolute address for the new agent to transfer the call to based on the resource information. The post-routing processor 410 transmits an address response with the absolute address to the call processing system 316. Once the call is completed, the call processing system 316 transmits the call information and service data to the call center report processor 414 for reporting purposes.

FIG. 8 depicts a message sequence chart for the call center resource 340. The call comes from the network element 336 via ATM link 338 to the ATM Switch 500. Using the absolute address in the call packets, the ATM switch 500 routes the call to the agent position 506. The service data comes from the network element 336 via ATM link 338 to the ATM Switch 500. Using the absolute address in the data packets, the ATM switch 500 routes the service data to the agent position 506. After the call is completed, the agent position 506 transmits call information to the call center resource processor 324 via the ATM network 502 and the control link 346. The call information could be caller number, called number, customer information, caller-entered digits/audio, and product/service information related to the call. Those skilled in the art will appreciate numerous variations in receiving calls by agent positions and interactive voice responses.

FIGS. 9-47 depict an example of systems that could be adapted by those skilled in the art to support the invention. In particular, the system described below will be adapted for use as communication systems 326 and 342 in FIG. 3.

The Controllable ATM Matrix

FIG. 9 illustrates an exemplary embodiment of a controllable asynchronous transfer mode (ATM) matrix (CAM), but other CAMs that support the requirements of the invention also are applicable. The CAM 902 may receive and transmit ATM formatted user communications or call signaling.

The CAM 902 preferably has a control interface 904, a controllable ATM matrix 906, an optical carrier-M/synchronous transport signal-M (OC-MWSTS-M) interface 908, and an OC-X/STS-X interface 910. As used herein in conjunction with OC or STS, “M” refers to an integer, and “X” refers to an integer.

The control interface 904 receives control messages originating from the signaling processor 912, identifies virtual connection assignments in the control messages, and provides these assignments to the matrix 906 for implementation. The control messages may be received over an ATM virtual connection and through either the OC-M/STS-M interface 908 or the OC-X/STS-X interface 910 through the matrix 906 to the control interface 904, through either the OC-M/STS-M interface or the OC-X/STS-X interface directly to the control interface, or through the control interface from a link.

The matrix 906 is a controllable ATM matrix that provides cross connect functionality in response to control messages from the signaling processor 912. The matrix 906 has access to virtual path/virtual channels (VP/VCs) over which it can connect calls. For example, a call can come in over a VPNVC through the OC-M/STS-M interface 908 and be connected through the matrix 906 over a VPNVC through the OC-X/STS-X interface 910 in response to a control message received by the signaling processor 912 through the control interface 904. Alternately, a call can be connected in the opposite direction. In addition, the a call can be received over a VPNVC through the OC-M/STS-M interface 908 or the OC-X/STS-X interface 910 and be connected through the matrix 906 to a different VPIVC on the same OC-M/STS-M interface or the same OC-X/STS-X interface.

The OC-M/STS-M interface 908 is operational to receive ATM cells from the matrix 906 and to transmit the ATM cells over a connection to the communication device 914. The OC-M/STS-M interface 908 also may receive ATM cells in the OC or STS format and transmit them to the matrix 906.

The OC-XISTS-X interface 910 is operational to receive ATM cells from the matrix 906 and to transmit the ATM cells over a connection to the communication device 916. The OC-X/STS-X interface 910 also may receive ATM cells in the OC or STS format and transmit them to the matrix 906.

Call signaling may be received through and transferred from the OC-M/STS-M interface 908. Also, call signaling may be received through and transferred from the OC-X/STS-X interface 910. The call signaling may be connected on a connection or transmitted to the control interface directly or via the matrix 906.

The signaling processor 912 is configured to transmit control messages to the CAM 902 to implement particular features on particular VP/VC circuits. Alternatively, lookup tables may be used to implement particular features for particular VP/VCs.

FIG. 10 illustrates another exemplary embodiment of a CAM which has time division multiplex (TDM) capability, but other CAMs that support the requirements of the invention also are applicable. The CAM 1002 may receive and transmit in-band and out-of-band signaled calls.

The CAM 1002 preferably has a control interface 1004, an OC-N/STS-N interface 1006, a digital signal level 3 (DS3) interface 1008, a DS1 interface 1010, a DSO interface 1012, an ATM adaptation layer (AAL) 1014, a controllable ATM matrix 1016, an OC-M/STS-M interface 1018A, an OC-X/STS-X interface 1018B, and an ISDN/GR-303 interface 1020. As used herein in conjunction with OC or STS, “N” refers to an integer, “M” refers to an integer, and “X” refers to an integer.

The control interface 1004 receives control messages originating from the signaling processor 1022, identifies DSO and virtual connection assignments in the control messages, and provides these assignments to the AAL 1014 or the matrix 1016 for implementation. The control messages may be received over an ATM virtual connection and through the OC-M/STS-M interface 1018A to the control interface 1004, through the OC-X/STS-X interface 1018B and the matrix 1016 to the control interface, or directly through the control interface from a link.

The OC-N/STS-N interface 1006, the DS3 interface 1008, the DS1 interface 1010, the DSO interface 1012, and the ISDN/GR-303 interface 1020 each can receive user communications from a communication device 1024. Likewise, the OC-M/STS-M interface 1018A and the OC-X/STS-X interface 1018B can receive user communications from the communication devices 1026 and 1028.

The OC-N/STS-N interface 1006 receives OC-N formatted user communications and STS-N formatted user communications and converts the user communications to the DS3 format. The DS3 interface 1008 receives user communications in the DS3 format and converts the user communications to the DS1 format. The DS3 interface 1008 can receive DS3s from the OC-N/STS-N interface 1006 or from an external connection. The DS1 interface 1010 receives the user communications in the DS1 format and converts the user communications to the DS0 format. The DS1 interface 1010 receives DS1s from the DS3 interface 1008 or from an external connection. The DS0 interface 1012 receives user communications in the DS0 format and provides an interface to the AAL 1014. The ISDN/GR-303 interface 1020 receives user communications in either the ISDN format or the GR-303 format and converts the user communications to the DS0 format. In addition, each interface may transmit user communications in like manner to the communication device 1024.

The OC-M/STS-M interface 1018A is operational to receive ATM cells from the AAL 1014 or from the matrix 1016 and to transmit the ATM cells over a connection to the communication device 1026. The OC-M/STS-M interface 1018A also may receive ATM cells in the OC or STS format and transmit them to the AAL 1014 or to the matrix 1016.

The OC-X/STS-X interface 1018B is operational to receive ATM cells from the AAL 1014 or from the matrix 1016 and to transmit the ATM cells over a connection to the communication device 1028. The OC-X/STS-X interface 1018B also may receive ATM cells in the OC or STS format and transmit them to the AAL 1014 or to the matrix 1016.

Call signaling may be received through and transferred from the OC-N/STS-N interface 1006 and the ISDN/GR-303 interface 1020. Also, call signaling may be received through and transferred from the OC-M/STS-M interface 1018A and the OCX/STS-X interface 1018B. The call signaling may be connected on a connection or transmitted to the control interface directly or via an interface as explained above.

The AAL 1014 comprises both a convergence sublayer and a segmentation and reassembly (SAR) sublayer. The AAL 1014 obtains the identity of the DS0 and the ATM VP/VC from the control interface 1004. The AAL 1014 is operational to convert between the DS0 format and the ATM format. AALs are known in the art, and information about AALs is provided by International Telecommunications Union (ITU) documents in the series of I.363, which are incorporated herein by reference. For example, ITU document I.363.1 discusses AAL1. An AAL for calls is described in U.S. Pat. No. 5,806,553 entitled “Cell Processing for Voice Transmission,” which is incorporated herein by reference.

Calls with multiple 64 Kilo-bits per second (Kbps) DS0s are known as N×64 calls. If desired, the AAL 1014 can be configured to accept control messages through the control interface 1004 for N×64 calls. The CAM 1002 is able to interwork, multiplex, and demultiplex for multiple DS0s. A technique for processing VP/VCs is disclosed in U.S. patent application Ser. No. 08/653,852, which was filed on May 28, 1996, and entitled “Telecommunications System with a Connection Processing System,” and which is incorporated herein by reference.

DS0 connections are bi-directional and ATM connections are typically uni-directional. As a result, two virtual connections in opposing directions typically will be required for each DS0. Those skilled in the art will appreciate how this can be accomplished in the context of the invention. For example, the cross-connect can be provisioned with a second set of VP/VCs in the opposite direction as the original set of VP/VCs.

The matrix 1016 is a controllable ATM matrix that provides cross connect functionality in response to control messages from the signaling processor 1022. The matrix 1016 has access to VP/VCs over which it can connect calls. For example, a call can come in over a VPIVC through the OC-M/STS-M interface 1018A and be connected through the matrix 1016 over a VP/VC through the OC-X/STS-X interface 1018B in response to a control message received by the signaling processor 1022 through the control interface 1004. Alternately, the matrix 1016 may transmit a call received over a VP/VC through the OC-M/STS-M interface 1018A to the AAL 1014 in response to a control message received by the signaling processor 1022 through the control interface 1004. Communications also may occur in opposite directions through the various interfaces.

In some embodiments, it may be desirable to incorporate digital signal processing capabilities at, for example, the DS0 level. It also may be desired to apply echo control to selected DS0 circuits. In these embodiments, a signal processor may be included. The signaling processor 1022 is configured to transmit control messages to the CAM 1002 to implement particular features on particular DS0 or VP/VC circuits. Alternatively, lookup tables may be used to implement particular features for particular circuits or VP/VCs.

It will be appreciated from the teachings above for the CAMs and for the teachings below for the ATM interworking units, that the above described CAMs can be adapted for modification to transmit and receive other formatted communications such as synchronous transport module (STM) and European level (E) communications. For example, the OC/STS, DS3, DS1, DS0, and ISDN/GR-303 interfaces can be replaced by STM electrical/optical (E/O), E3, E1, E0, and digital private network signaling system (DPNSS) interfaces, respectively.

If desired, the AAL 1116 can be configured to accept control messages through the control interface 1104 for N×64 calls. The ATM interworking unit 1102 is able to interwork, multiplex, and demultiplex for multiple DS0s.

Those skilled in the art will appreciate how this can be accomplished in the context of the invention. For example, the cross-connect can be provisioned with a second set of VP/VCs in the opposite direction as the original set of VP/VCs.

In some embodiments, it may be desirable to incorporate digital signal processing capabilities at the DS0 level. It may also be desired to apply echo control to selected DS0 circuits. In these embodiments, a signal processor 1114 is included either separately (as shown) or as a part of the DS0 interface 1112. The signaling processor 1122 is configured to transmit control messages to the ATM interworking unit 1102 to implement particular features on particular DS0 circuits. Alternatively, lookup tables may be used to implement particular features for particular circuits or VP/VCs.

FIG. 12 illustrates another exemplary embodiment of an interworking unit which is an ATM interworking unit 1202 suitable for the present invention for use with an SDH system. The ATM interworking unit 1202 preferably has a control interface 1204, an STM-N electrical/optical (E/O) interface 1206, an E3 interface 1208, an E1 interface 1210, an E0 interface 1212, a signal processor 1214, an AAL 1216, an STM-M electrical/optical (E/O) interface 1218, and a DPNSS interface 1220. As used herein in conjunction with STM, “N” refers to an integer, and “M” refers to an integer.

The control interface 1204 receives control messages from the signaling processor 1222, identifies E0 and virtual connection assignments in the control messages, and provides these assignments to the AAL 1216 for implementation. The control messages are received over an ATM virtual connection and through the STM-M interface 1218 to the control interface 1104 or directly through the control interface from a link.

The STM-N E/O interface 1206, the E3 interface 1208, the E1 interface 1210, the E0 interface 1212, and the DPNSS interface 1220 each can receive user communications from a second communication device 1224.

The AAL 1216 is operational to convert between the E0 format and the ATM format, either in response to a control instruction or without a control instruction. AAL's are known in the art. If desired, the AAL 1216 can be configured to receive control messages through the control interface 1204 for N×64 user communications.

E0 connections are bi-directional and ATM connections typically are uni-directional. As a result, two virtual connections in opposing directions typically will be required for each E0. Those skilled in the art will appreciate how this can be accomplished in the context of the invention.

In some instances, it may be desirable to incorporate digital signal processing capabilities at the E0 level. Also, it may be desirable to apply echo control. In these embodiments, a signal processor 1214 is included either separately (as shown) or as a part of the E0 interface 1212. The signaling processor 1222 is configured to transmit control messages to the ATM interworking unit 1202 to implement particular features on particular circuits. Alternatively, lookup tables may be used to implement particular features for particular circuits or VP/VCs.

The Signaling Processor

The signaling processor receives and processes telecommunications call signaling, control messages, and customer data to select connections that establish communication paths for calls. In the preferred embodiment, the signaling processor processes SS7 signaling to select connections for a call. An example of call processing in a call processor and the associated maintenance that is performed for call processing is described in a U.S. patent application Ser. No. 09/026,766 entitled “System and Method for Treating a Call for Call Processing,” which is incorporated herein by reference.

In addition to selecting connections, the signaling processor performs many other functions in the context of call processing. It not only can control routing and select the actual connections, but it also can obtain an absolute address, validate callers, control echo cancellers, generate accounting information, invoke intelligent network functions, access remote databases, manage traffic, and balance network loads. One skilled in the art will appreciate how the signaling processor described below can be adapted to operate in the above embodiments.

FIG. 13 depicts an embodiment of a signaling processor. Other versions also are contemplated. In the embodiment of FIG. 13, the signaling processor 1302 has a signaling interface 1304, a call processing control system 1306 (CPCS), and a call processor 1308. It will be appreciated that the signaling processor 1302 may be constructed as modules in a single unit or as multiple units.

The signaling interface 1304 is coupled externally to signaling systems1—preferably to signaling systems having a message transfer part (MTP), an ISDN user part (ISUP), a signaling connection control part (SCCP), an intelligent network application part (INAP), and a transaction capabilities application part (TCAP). The signaling interface 1304 preferably is a platform that comprises an MTP level 1 1310, an MTP level 2 1312, an MTP level 3 1314, an SCCP process 1316, an ISUP process 1318, and a TCAP process 1320. The signaling interface 1304 also has INAP functionality.

The signaling interface 1304 may be linked to a communication device (not shown). For example, the communication device may be an SCP which is queried by the signaling interface with a TCAP query to obtain additional call-associated data. The answer message may have additional information parameters that are required to complete call processing. The communication device also may be an STP or other device.

The signaling interface 1304 is operational to transmit, process, and receive call signaling. The TCAP, SCCP, ISUP, and INAP functionality use the services of the MTP to transmit and receive the messages. Preferably, the signaling interface 1304 transmits and receives SS7 messages for MTP, TCAP, SCCP, and ISUP. Together, this functionality is referred to as an “SS7 stack,” and it is well known. The software required by one skilled in the art to configure an SS7 stack is commercially available. One example is the OMNI SS7 stack from Dale, Gesek, McWilliams & Sheridan, Inc. (the DGM&S company).

The processes of the signaling interface 1304 process information that is received in message signal units (MSUs) and convert the information to call information elements that are sent to the call processor 1308 to be processed. A call information element may be, for example, an ISUP IAM message parameter from the MSU. The signaling interface 1304 strips the unneeded header information from the MSU to isolate the message information parameters and passes the parameters to the call processor 1308 as the call information elements. Examples of these parameters are the called number, the calling number, and user service information. Other examples of messages with information elements are an ANM, an ACM, an REL, an RLC, and an INF. In addition, call information elements are transferred from the call processor 1308 back to the signaling interface 1304, and the information elements are reassembled into MSUs and transferred to a signaling point.

The CPCS 1306 is a management and administration system. The CPCS 1306 is the user interface and external systems interface into the call processor 1308. The CPCS 1306 serves as a collection point for call-associated data such as logs, operational measurement data, statistical information, accounting information, and other call data. The CPCS 1306 can configure the call-associated data and/or transmit it to reporting centers.

The CPCS 1306 accepts data, such as the translations, from a source such as an operations system and updates the data in the tables in the call processor 1308. The CPCS 1306 ensures that this data is in the correct format prior to transferring the data to the call processor 1308. The CPCS 1306 also provides configuration data to other devices including the call processor 1308, the signaling interface 1304, the interworking unit (not shown), and the controllable ATM matrix (not shown). In addition, the CPCS 1306 provides for remote control of call monitoring and call tapping applications from the call processor 1308.

The CPCS 1306 also serves as a collection point for alarms. Alarm information is transferred to the CPCS 1306. The CPCS 1306 then transports alarm messages to the required communication device. For example, the CPCS 1306 can transport alarms to an operations center.

The CPCS 1306 also has a human-machine interface (HMI). This allows a person to log onto the CPCS 1306 and manage data tables or review data tables in the CPCS or provide maintenance services.

The call processor 1308 processes call signaling and controls an ATM interworking unit, such as an ATM interworking multiplexer (mux) that performs interworking of DS0s and VP/VCs, and an ATM matrix. However, the call processor 1308 may control other communications devices and connections in other embodiments.

The call processor 1308 comprises a control platform 1322 and an application platform 1324. Each platform 1322 and 1324 is coupled to the other platform.

The control platform 1322 is comprised of various external interfaces including an interworking unit interface, a controllable ATM matrix, an echo interface, a resource control interface, a call information interface, and an operations interface. The control platform 1322 is externally coupled to an interworking unit control, a controllable ATM matrix control, an echo control, a resource control, accounting, and operations. The interworking unit interface exchanges messages with at least one interworking unit. These messages comprise DS0 to VP/VC assignments, acknowledgments, and status information. The controllable ATM matrix interface exchanges messages with at least one controllable ATM matrix. These messages comprise DS0 to VP/VC assignments, VP/VC to VP/VC assignments, acknowledgments, and status information. The echo control interface exchanges messages with echo control systems. Messages exchanged with echo control systems might include instructions to enable or disable echo cancellation on particular DS0s, acknowledgments, and status information.

The resource control interface exchanges messages with external resources. Examples of such resources are devices that implement continuity testing, encryption, compression, tone detection/transmission, voice detection, and voice messaging. The messages exchanged with resources are instructions to apply the resource to particular DS0s, acknowledgments, and status information. For example, a message may instruct a continuity testing resource to provide a loopback or to transmit and detect a tone for a continuity test.

The call information interface transfers pertinent call information to a call information processing system, such as to the CPCS 1306. Typical call information includes accounting information, such as the parties to the call, time points for the call, and any special features applied to the call. One skilled in the art will appreciate how to produce the software for the interfaces in the control platform 1322.

The application platform 1324 processes signaling information from the signaling interface 1304 to select connections. The identity of the selected connections are provided to the control platform 1322 for the interworking unit interface and/or for the controllable ATM matrix interface. The application platform 1324 is responsible for validation, translation, routing, call control, exceptions, screening, and error handling. In addition to providing the control requirements for the interworking unit and the controllable ATM matrix, the application platform 1324 also provides requirements for echo control and resource control to the appropriate interface of the control platform 1322. In addition, the application platform 1324 generates signaling information for transmission by the signaling interface 1304. The signaling information might be for ISUP, INAP, or TCAP messages to external network elements. Pertinent information for each call is stored in an enhanced circuit data block (ECDB) for the call. The ECDB can be used for tracking and accounting the call.

The application platform 1324 preferably operates in general accord with the Basic Call State Model (BCSM) defined by the ITU. An instance of the BCSM is created to handle each call. The BCSM includes an originating process and a terminating process. The application platform 1324 includes a service switching function (SSF) that is used to invoke the service control function (SCF). Typically, the SCF is contained in an SCP. The SCF is queried with TCAP or INAP messages that are transported by the signaling interface 1304 and which are initiated with information from the SSF in the application platform 1324. The originating or terminating processes will access remote databases with intelligent network (IN) functionality via the SSF.

Software requirements for the application platform 1324 can be produced in specification and description language (SDL) defined in ITU-T Z.100 or similar logic or description languages. The SDL can be converted into C code. A real time case tool such as SDT from Telelogic, Inc. or Object Time from Object Time, Inc. can be used. Additional C and C++ code can be added as required to establish the environment. It will be appreciated that other software languages and tools may be used.

The call processor 1308 can be comprised of the above-described software loaded onto a computer. The computer can be a generally available fault-tolerant Unix computer, such as those provided by Sun, Tandem, or Hewlett Packard. It may be desirable to utilize the multi-threading capability of a Unix operating system.

From FIG. 13, it can be seen that the application platform 1324 processes signaling information to control numerous systems and facilitate call connections and services. The SS7 signaling is exchanged between the call processor 1308 and external components through the signaling interface 1304, and control information is exchanged with external systems through the control platform 1322. Advantageously, the signaling interface 1304, the CPCS 1306, and the call processor 1308 are not integrated into a switch central processing unit (CPU) that is coupled to a switching matrix. Unlike an SCP, the components of the signaling processor 1302 are capable of processing ISUP messages independently of TCAP queries.

Call Processor Tables

Call processing typically entails two aspects. First, an incoming or “originating” connection is recognized by an originating call process. For example, the initial connection that a call uses to enter a network is the originating connection in that network. Second, an outgoing or “terminating” connection is selected by a terminating call process. For example, the terminating connection is coupled to the originating connection in order to extend the call through the network. These two aspects of call processing are referred to as the originating side of the call and the terminating side of the call.

FIG. 14 depicts an exemplary data structure preferably used by the call processor 1302 of FIG. 13 to execute the BCSM. This is accomplished through a series of tables that point to one another in various ways. The pointers typically are comprised of next function and next label designations. The next function points to the next table, and the next label points to an entry or a range of entries in that table. It will be appreciated that the pointers for the main call processing are illustrated in FIG. 14.

The primary data structure has a TDM trunk circuit table 1402, an ATM trunk circuit table 1404, a trunk group table 1406, a carrier table 1408, an exception table 1410, an originating line information (OLI) table 1412, an automatic number identification (ANI) table 1414, a called number screening table 1416, a called number table 1418, a routing table 1420, a trunk group class of service (COS) table 1422, and a message mapping table 1424. Also included in the data structure are a day of year table 1426, a day of week table 1428, a time of day table 1430, and a time zone table 1432.

The TDM trunk circuit table 1402 contains information required to provision the TDM side of a connection from the call processor site. Each circuit on the TDM side of a connection has an entry. The TDM trunk circuit table 1402 is accessed from the trunk group table 1406 or an external call process, and it points to the trunk group table.

The ATM trunk circuit table 1404 contains information required to provision the ATM side of a connection. Typically, one record appears in this table per ATM trunk group. Although, the system can be configured alternately for multiple records per trunk group. The ATM trunk circuit table 1404 is accessed from the trunk group table 1406 or an external call process, and it points to the trunk group table.

The trunk group table 1406 contains information that is required to build trunk groups out of different trunk members identified in the TIDM and ATM trunk circuit tables 1402 and 1404. The trunk group table 1406 contains information related to the originating and terminating trunk groups. The trunk group table 1406 typically points to the carrier table 1408. Although, the trunk group table 1406 may point to the exception table 1410, the OLI table 1412, the ANI table 1414, the called number screening table 1416, the called number table 1418, the routing table 1420, the day of year table 1426, the day of week table 1428, the time of day table 1430, and the treatment table (see FIG. 15).

For default processing of an IAM of an outgoing call in the forward direction, when the call process determines call setup and routing parameters for user communications on the originating portion, the trunk group table 1406 is the next table after the TDM and ATM trunk circuit tables 1402 and 1404, and the trunk group table points to the carrier table 1408. For default processing of an IAM of an outgoing call in the forward direction, when the call process determines call setup and routing parameters for user communications on the terminating portion, the trunk group table 1406 is the next table after the routing table 1420, and the trunk group table points to the TDM or ATM trunk circuit table 1402 or 1404. For default processing of an ACM or an ANM of an outgoing call in the originating direction, when the call process determines parameters for signaling, the trunk group table 1406 is the next table after the TDM or ATM trunk circuit table 1402 or 1404, and the trunk group table points to the message mapping table 1424. It will be appreciated that this is the default method, and, as explained herein, other implementations of table processing occur.

The carrier table 1408 contains information that allows calls to be screened based, at least in part, on the carrier information parameter and the carrier selection parameter. The carrier table 1408 typically points to the exception table 1410. Although, the carrier table 1408 may point to the OLI table 1412, the ANI table 1414, the called number screening table 1416, the called number table 1418, the routing table 1420, the day of year table 1426, the day of week table 1428, the time of day table 1430, the treatment table (see FIG. 15), and the database services table (see FIG. 16).

The exception table 1410 is used to identify various exception conditions related to the call that may influence the routing or handling of the call. The exception table 1410 contains information that allows calls to be screened based, at least in part, on the called party number and the calling party's category. The exception table 1410 typically points to the OLI table 1412. Although, the exception table 1410 can point to the ANI table 1414, the called number screening table 1416, the called number table 1418, the routing table 1420, the day of year table 1426, the day of week table 1428, the time of day table 1430, the call rate table, the percent control table, the treatment table (see FIG. 15), and the database services table (see FIG. 16).

The OLI table 1412 contains information that allows calls to be screened based, at least in part, on originating line information in an lAM. The OLI table 1412 typically points to the ANI table 1414. Although, the OLI table can point to the called number screening table 1416, the called number table 1418, the routing table 1420, the day of year table 1426, the day of week table 1428, the time of day table 1430, and the treatment table (see FIG. 15).

The ANI table 1414 is used to identify any special characteristics related to the caller's number, which is commonly known as automatic number identification. The ANI table 1414 is used to screen and validate an incoming ANI. ANI specific requirements such as queuing, echo cancellation, time zone, and treatments can be established. The ANI table 1414 typically points to the called number screening table 1416. Although, the ANI table 1414 can point to the called number table 1418, the routing table 1420, the day of year table 1426, the day of week table 1428, the time of day table 1430, and the treatment table (see FIG. 15).

The called number screening table 1416 is used to screen called numbers. The called number screening table 1416 determines the disposition of the called number and the nature of the called number. The called number screening table 1416 is used to provide the trigger detection point (TDP) for an AIN SCP TCAP query. It is used, for example, with the local number portability (NP) feature. The called number screening table can invoke a TCAP. The called number screening table 1416 typically points to the called number table 1418. Although, the called number screening table 1416 can point to the routing table 1420, the treatment table, the call rate table, the percent table (see FIG. 15), and the database services table (see FIG. 16).

The called number table 1418 is used to identify routing requirements based on, for example, the called number. This will be the case for standard calls. The called number table 1418 typically points to the routing table 1410. In addition, the called number table 1426 can be configured to alternately point to the day of year table 1426. The called number table 1418 can also point to the treatment table (see FIG. 15) and the database services table (see FIG. 16).

The routing table 1420 contains information relating to the routing of a call for various connections. The routing table 1420 typically points to the treatment table (see FIG. 15). Although, the routing table also can point to the trunk group table 1406 and the database services table (see FIG. 16).

For default processing of an IAM of an outgoing call in the forward direction, when the call process determines call setup and routing parameters for user communications, the routing table 1420 is the next table after the called number table 1418, and the routing table points to the trunk group table 1406. For default processing of an IAM of an outgoing call in the forward direction, when the call process determines parameters for signaling, the routing table 1420 is the next table after the called number table 1418, and the routing table points to the message mapping table 1424. It will be appreciated that this is the default method, and, as explained herein, other implementations of table processing occur.

The trunk group COS table 1422 contains information that allows calls to be routed differently based on the class of service assigned to the originating trunk group and to the terminating trunk group. The trunk group COS table can point to the routing table 1420 or the treatment table (see FIG. 15).

When the trunk group COS table 1422 is used in processing, after the routing table 1420 and the trunk group table 1406 are processed, the trunk group table points to the trunk group COS table. The trunk group COS table points back to the routing table 1420 for further processing. Processing then continues with the routing table 1420 which points to the trunk group table 1406, and the trunk group table which points to the TDM or ATM trunk circuit table 1402 or 1404. It will be appreciated that this is the default method, and, as explained herein, other implementations of table processing occur.

The message mapping table 1424 is used to provide instructions for the formatting of signaling messages from the call processor. It typically can be accessed by the routing table 1420 or the trunk group table 1406 and typically determines the format of the outgoing messages leaving the call processor.

The day of year table 1426 contains information that allows calls to be routed differently based on the day of the year. The day of year table typically points to the routing table 1420 and references the time zone table 1432 for information. The day of year table 1426 also can point to the called number screening table 1416, the called number table 1418, the routing table 1420, the day of week table 1428, the time of day table 1430, and the treatment table (see FIG. 15).

The day of week table 1428 contains information that allows calls to be routed differently based on the day of the week. The day of week table typically points to the routing table 1420 and references the time zone table 1432 for information. The day of week table 1428 also can point to the called number screening table 1416, the called number table 1418, the time of day table 1430, and the treatment table (see FIG. 15).

The time of day table 1430 contains information that allows calls to be routed differently based on the time of the day. The time of day table 1430 typically points to the routing table 1420 and references the time zone table 1432 for information. The time of day table 1430 also can point to the called number screening table 1416, the called number table 1418, and the treatment table (see FIG. 15).

The time zone table 1432 contains information that allows call processing to determine if the time associated with the call processing should be offset based on the time zone or daylight savings time. The time zone table 1432 is referenced by, and provides information to, the day of year table 1426, the day of week table 1428, and the time of day table 1430.

FIG. 15 is an overlay of FIG. 14. The tables from FIG. 14 are present. However, for clarity, the table's pointers have been omitted, and some tables have not been duplicated in FIG. 15. FIG. 15 illustrates additional tables that can be accessed from the tables of FIG. 14. These include an outgoing release table 1502, a treatment table 1504, a call rate table 1506, and a percent control table 1508, and time/date tables 1510.

The outgoing release table 1502 contains information that allows call processing to determine how an outgoing release message is to be formatted. The outgoing release table 1502 typically points to the treatment table 1506.

The treatment table 1504 identifies various special actions to be taken in the course of call processing. For example, based on the incoming trunk group or ANI, different treatments or cause codes are used to convey problems to the called and calling parties. This typically will result in the transmission of a release message (REL) and a cause value. The treatment table 1504 typically points to the outgoing release table 1502 and the database services table (see FIG. 16).

The call rate table 1506 contains information that is used to control call attempts on an attempt per second basis. Preferably, attempts from 100 per second to 1 per minute are programmable. The call rate table 1506 typically points to the called number screening table 1416, the called number table 1418, the routing table 1420, and the treatment table 1504.

The percent control table 1508 contains information that is used to control call attempts based upon a percent value of the traffic that is processed through call processing. The percent control table 1508 typically points to the called number screening table 1416, the called number table 1418, the routing table 1420, and the treatment table 1504.

The date/time tables 1510 have been identified in FIG. 14 as the day of year table 1426, the day of week table 1428, the time of day table 1426, and the time zone table 1432. They are illustrated in FIG. 15 as a single location for ease and clarity but need not be so located.

FIG. 16 is an overlay of FIGS. 14-15. The tables from FIGS. 14-15 are present. However, for clarity, the table's pointers have been omitted, and some tables have not been duplicated in FIG. 16.

FIG. 16 illustrates additional tables that can be accessed from the tables of FIGS. 14-15 and which are directed to the TCAP and the SCCP message processes. These include a database services table 1602, a signaling connection control part (SCCP) table 1604, an intermediate signaling network identification (ISNI) table 1606, a transaction capabilities application part (TCAP) table 1608, and an advanced intelligent network (AIN) event parameters table 1610.

The database services table 1602 contains information about the type of database service requested by call processing. The database services table 1602 references and obtains information from the SCCP table 1604 and the TCAP table 1608. After the database function is performed, the call is returned to normal call processing. The database services table 1602 points to the called number table 1418.

The SCCP table 1604 contains information and parameters required to build an SCCP message. The SCCP table 1604 is referenced by the database services table 1602 and provides information to the database services table.

The ISNI table 1606 contains network information that is used for routing SCCP message to a destination node. The ISNI table 1606 is referenced by the SCCP table 1604 and provides information to the SCCP table.

FIG. 17 is an overlay of FIGS. 14-16. The tables from FIGS. 14-16 are present. However, for clarity, the tables have not been duplicated in FIG. 17. FIG. 17 illustrates additional tables that can be used to setup the call process so that the tables of FIGS. 14-16 may be used. These setup tables 1702 include a site office table 1704, an external echo canceller table 1706, an interworking unit (IWU) table 1708, a controllable ATM matrix (CAM) interface table 1710, and a controllable ATM matrix (CAM) table 1712.

The site office table 1704 contains information which lists office-wide parameters, some of which are information-based and others which affect call processing. The site office table 1704 provides information to the call processor or switch during initialization or other setup procedures, such as population of data or transfer of information to one or more memory locations for use during call processing.

The external echo canceller 1706 contains information that provides the interface identifier and the echo canceller type when an external echo canceller is required. The external echo canceller table 1706 provides information to the call processor or switch during initialization or other setup procedures, such as population of data or transfer of information to one or more memory locations for use during call processing.

The IWU table 1708 contains the internet protocol (IP) identification numbers for interfaces to the interworking units at the call processor or switch site. The IWU table 1708 provides information to the call processor or switch during initialization or other setup procedures, such as population of data or transfer of information to one or more memory locations for use during call processing.

The CAM interface table 1710 contains information for the logical interfaces associated with the CAM. The CAM interface table 1710 provides information to the call processor or switch during initialization or other setup procedures, such as population of data or transfer of information to one or more memory locations for use during call processing.

The CAM table 1712 contains information associated with the logical and physical setup properties of the CAM. The CAM table 1712 provides information to the call processor or switch during initialization or other setup procedures, such as population of data or transfer of information to one or more memory locations for use during call processing.

FIGS. 23-52 depict examples of the various tables described above. It will be appreciated that other versions of tables may be used. In addition, information from the identified tables may be combined or changed to form different tables.

FIG. 18 depicts an example of a TDM trunk circuit table. The TDM trunk circuit table is used to access information about the originating circuit for originating circuit call processing. It also is used to provide information about the terminating circuit for terminating circuit call processing. The trunk group number of the circuit associated with the call is used to enter the table. The group member is the second entry that is used as a key to identify or fill information in the table. The group member identifies the member number of the trunk group to which the circuit is assigned, and it is used for the circuit selection control.

The table also contains the trunk circuit identification code (TCIC). The TCIC identifies the trunk circuit which is typically a DS0. The echo canceller (EC) label entry identifies the echo canceller, if any, which is connected to the circuit. The interworking unit (IWU) label and the interworking unit (IWU) port identify the hardware location and the port number, respectively, of the interworking unit. The DS1/E1 label and the DS1/E1 channel denote the DS1 or the E1 and the channel within the DS1 or E1, respectively, that contains the circuit. The initial state specifies the state of the circuit when it is installed. Valid states include blocked if the circuit is installed and blocked from usage, unequipped if the circuit is reserved, and normal if the circuit is installed and available from usage.

FIG. 19 depicts an example of an ATM trunk circuit table. The ATM trunk circuit table is used to access information about the originating circuit for originating circuit call processing. It also is used to provide information about the terminating circuit for terminating circuit call processing.

The trunk group number of the circuit associated with the call is used to enter the table. The group size denotes the number of members in the trunk group. The starting trunk circuit identification code (TCIC) is the starting TCIC for the trunk group, and it is used in the routing label of an ISUP message. The transmit interface label identifies the hardware location of the virtual path on which the call will be transmitted. The transmit interface label may designate either an interworking unit interface or a CAM interface for the designated trunk members. The transmit virtual path identifier (VPI) is the VP that will be used on the transmission circuit side of the call. The receive interface label identifies the hardware location of the virtual path on which the call will be received. The receive interface label may designate either an interworking unit interface or a CAM interface for the designated trunk members. The receive virtual path identifier (VPI) is the VP that will be used on the reception circuit side of the call. The initial state specifies the state of the circuit when it is installed. Valid states include blocked if the circuit is installed and blocked from usage, unequipped if the circuit is reserved, and normal if the circuit is installed and available from usage.

FIG. 20A depicts an example of a trunk group table. The trunk group number of the trunk group associated with the circuit is used to key into the trunk group table. The administration information field is used for information purposes concerning the trunk group and typically is not used in call processing. The associated point code is the point code for the far end switch or call processor to which the trunk group is connected. The common language location identifier (CLLI) entry is a standardized Bellcore entry for the associated office to which the trunk group is connected. The trunk type identifies the type of the trunk in the trunk group. The trunk type may be a TDM trunk, an ATM trunk from the interworking unit, or an ATM trunk from the CAM.

The associated numbering plan area (NPA) contains information identifying the switch from which the trunk group is originating or to which the trunk group is terminating. The associated jurisdiction information parameter (JIP) contains information identifying the switch from which the trunk group is originating or to which the trunk group is terminating. If an ISUP TIP is not received in an IAM, the default JIP is a value recorded on the call processor ECDB. If an incoming IAM does not have a JIP, call processing will populate the JIP of the outgoing IAM with the default value from the trunk group table. If a JIP is not data filled, an outgoing JIP is not transmitted.

The time zone label identifies the time zone that should be used when computing a local date and a local time for use with a day of year table, the day of week table, and the time of day table. The echo canceller information field describes the trunk group echo cancellation requirements. Valid entries for the echo canceller information include normal for a trunk group that uses internal echo cancellation, external for a trunk group that requires external echo cancellers, and disable for a trunk group that requires no echo cancellation for any call passing over the group.

FIG. 20B is a continuation of FIG. 20A for the trunk group table. The satellite entry specifies that the trunk group for the circuit is connected through a satellite. If the trunk group uses too many satellites, then a call should not use the identified trunk group. This field is used in conjunction with the nature of connection satellite indicator field from the incoming IAM to determine if the outgoing call can be connected over this trunk group. The select sequence indicates the methodology that will be used to select a connection. Valid entries for the select sequence field include the following: most idle, least idle, ascending, or descending. The interworking unit (IWU) priority signifies that outgoing calls will attempt to use a trunk circuit on the same interworking unit before using a trunk circuit on a different interworking unit.

Glare resolution indicates how a glare situation is to be resolved. Glare is the dual seizure of the same circuit. If the glare resolution entry is set to “even/odd,” the switch or the call processor with the higher point code value will control the even number TCICs within the trunk group. The switch or call processor with the lower point code value will control the odd number TCICs.
